Study on the influence of voids on high-rise building on the wind environment

Li, Yangluxi; Chen, Lei

After that, taking consideration of large scale urban circumstance, porous model started to be used for performing natural airflow characteristic under city scale. Li (2010, 2012) regarded whole urban area as a combination of porous and fluid model to investigate city thermal and airflow environment. In addition, a new code called "Ventair" code based on FORTRAN language was created to check this porous model. On this scale, Wang et al. (2017) also adopted a mixed model of fully resolved and porous model to simulate the urban thermal and wind environment. All buildings and surroundings were set as porous model. Apart from this, so as to simplified simulation process, Antohe and Lage (1997) established a two-equation porous model which is identical with standard k-ε model in terms of the closure coefficients.
